To' il wlw-m amy mest- Be it known thataI JOHN F. lvuiuun",A aA

citizen ofthe United tates, residin, 1;.atChi-l` cago, county of Cook,and State of Illinois,

have invented certain new-and'useful Im- Jrovements in' Safet -Razors`,of which the ollowing `is a specification.

safety razors.

The object of my invention-is the provision of a razor of the charactermentioned in* which the razor blade may be readily adjusted relative tothe guard which coacts therewith to effect -the regulation of thevcloseness ofthe shave. i

further object .is ai@ pfovisin of razor asr'nentionedwhicli ma bearranged;

slidiiigjdiagonal-stroke for cross-stroke-or shaving. v l

A further -object'is the provision'Aof-a safety razor which will beofvdurable andcconoinical construction and-etlicicnt--in op-vv Otherobjects will appear hereinafter. -With these 4ob'ects 41n .view myinvention `consists in a sa ety razon-characterized as` above mentionedand in certaindeta'ilsfof construction and arrangement of arts all* aswill be hereinafter fully descri edand.A (particularly pointed out inthe ap "10H5 pende M stoo drawings formin a part of this specifica-vtion, and in whic 'A 1' Figure 1 yis a side elevation lof a razorcinbodyin the preferred form ofmy invention, iig. 2 is a topy planview'thereof,

Fili'` 3 is a section taken on line m--ai'of Fig. 1, ig. 4 is asectional side elevation-of the razor assembled in a mannerslightly'ditier-Y ent from that shown in Figs. 1, 2 and 3 Fig. 5 is anend elevation of the 'upper-,end

portion thereof, and Fig. (l is a perspective view ofthe blade detached.

Referring now to the drawing 1l indicates the head' of the razor and 2thehandle thereof. Arran ed in the .head 1; is the blade 8. Said b adeis thin andtiat in form,.

the longitudinal or cutting edges 3 thereof bein singularly ordivergently disposed and' pre erably beveledy as indioatedfjgProvided.substantially centrally in the'5-bladej-:1g-'are aiplarality of'slots orop'e'ningsi.4,`'there-bef` ing preferably three in number, said slots.

invention relates to razors and more specifically tothat class thereof,-known as the longitudinal invention will be more readily:n'i'ider-lf1 byreference to the accompanyingbein arranged in a line coincident with orpara lel to the center line of said blade. Arranged -upon the upper sideof said blade is a flat cover late 5 of a shape similar to that of saidbla e, the same being of a length substantially the same as that of thelatter, but of a width such that, when said plate is properly arrangedcentrally upon said blade, edges thereof will be Slightly spaced fromthe edges 3 of the blade, as clearly shown in Figs. 2 and i.

Formed centrally upon the under side of the plate 5 are spacedprojecting studs 6 and intermediate ,the latter a threaded stud ,7. Saidstuds are positioned for registration with and for snug enaagement ofthe slots ltiformed in the bla e 3, said slots being stuare in order toconform with the shape o the studs 6 and the base portion of the stud 7which, together with the studs 6, is

square in crosssection, as clearly shown in Fig. .8. Arranged upontheundcr side of theblade 1 is a guard plate 8 of a shape similar tothatof-the plate 5 and the blade 8,:the same being of a length slightlygreater than that of said parte, and ofa width suchthatthelongitudinaledges 9 thereof project slightlyfbeyond'the `cuttingedges of said blade to constitute aguard for the skin` when shavingUSaidlongitudinal edges 9 of said guard plate are toothed as indicated forapurpose' well known. qv-...Provided centrally in the plate 8 is aplurality of slots 10 elongated in a direction lon itudinally extendingof said plate.

Sai slots are positioned for engagement bv studs 6 and 7 the same beingof a width substantially t e same as that. `of said studs ermitting oflongitudinal movement. of tho atter therein, but reventing relativetransverse movement. Vth thisV construction it will be seen thatlongitudinal adjustment of Athe blade and cover plate upon the guardplate is permitted and whereby the 'adjacency of the cutting edges ofthe blade to the` guard edges of the guard plate may be varied asdesired in order to regulate the closeness of the shave desired withoutexposing the blade.

1A 0ne'end of the handle 2 of the razor is flattened as at 12 at oneside. the samel being provided with two spaced transversely ,extendingopenings 13 and 14. Said open ings 13 and 14 are formed and spaced forthc snug reception of the stud 7 and one of said` studs 4t3respectively, and whereby,

through the xmedium of a thumb nut 15 threaded upon theouter end of thestud 7 for' engagement of the outer side of said end portion of thehandle, the head 1 of the razor may be rigidly secured to said handle.When so arranged, it is evident, the razor may be manipulated as anordinary razor for slidingdia,gonalstroke shaving.

The opposite end of tlre handle is provided .with a longitudinallyextending tapped recess 16 which is adapted to receive 'and be threadedupon the stud 7, as shown in Figs.

- 5 and 6. When so arranged the device may evidently be used as safetyrazors now gen erally in use, for cross-stroke shaving. In

.the former employment.- the nut 15, and in the latter, the handleitself, serves to clampingly lock the parts of the razor head inoperative position, so that, in order to adjust said parts, it is onlyrequired to slightly rotate said nut or handle, as the case may be,whereupon free adjustment of said parts will be permitted. A

A razor of a construction as set forth pre- Sents a durable andeconomical construction of low cost to manufacture, all parts thereofmay be readily detached for cleaning, and

` the same permits of ready .and expeditious claim as new and desire tosecure by Letters Patent is:

1. A safety razor comprising a flat blade having angularly disposedcutting edges and centrally arranged' openings; a guard plate and acover plate on opposite sides of said blade, there being elongated slotsin said guard plateregisteriug with said openings;

-studs upon the inner surface of said cover plate projecting therefromthrough said openings and slots in said blade and guard plate; and meanscooperating with said studs for clamping said blade and cover plate inoperative relationship, substantially as described.

2. A safety razor comprising a flat blade having a cutting edge andcentrally arranged openings; a guard plate and a cover vplate onopposite sides of said blade, there lbeing elongated slots in said guardplate registering with said openings; studs upon the inner surface ofsaid cover plate projecting therefrom through said openings and slots insaid blade and guard plate, said slots being so positioned-that slidingof said cover platev and said blade upon` said guard plate adjusts theadjacency of the cutting.

edge of said blade with the guarding edge of said guard plate; and aVhandle coperating with said studs to clamp said blade and guard platein operative relationship, substantially as described.

In' testimony/whereof I have signed my name to this specification in thepresence of l 'two subscribing Witnesses.
